Week 38 Day 2: The Three-Bucket Retirement: Short, Medium, and Long

Bucket 1 (Cash): 1-3 years of living expenses in a high-yield savings account. This covers your expenses even if the market crashes tomorrow. You never need to sell stocks during a downturn. Bucket 2 (Bonds): 3-10 years of expenses in bond funds (VCIT, BND). Provides stability and income. Refills Bucket 1 as it depletes. Bucket 3 (Stocks): everything else in stock funds (VTI, SCHD). This bucket grows over time and refills Bucket 2.

The three-bucket system in practice: Example: $1.5 million portfolio, $60,000/year spending. Bucket 1 (Cash): $120,000-$180,000 (2-3 years). Earning 4-5% in a high-yield savings account. Bucket 2 (Bonds): $300,000-$420,000 (5-7 years). In bond index funds, earning 4-5%. Bucket 3 (Stocks): $900,000-$1,080,000 (15+ years). In VTI/SCHD, earning 7-10% long-term. How it works during a crash: The market drops 40%. Your stocks are down. But you do not need to sell stocks -- you live off Bucket 1 (cash) for 2-3 years while stocks recover. Historically, the market has recovered from every crash within 1-5 years. When Bucket 1 gets low (down to 1 year of expenses), refill it from Bucket 2 (sell some bonds). When Bucket 2 gets low, refill from Bucket 3 (sell some stocks -- presumably recovered). When stocks boom: the reverse. Take some gains from Bucket 3 and move them to Bucket 2 and Bucket 1. This is the bucket equivalent of rebalancing. The psychological benefit: knowing that 2-3 years of expenses are safe in cash eliminates the panic that causes retirees to sell stocks at the worst possible time. The system buys time for stocks to recover without requiring the retiree to make any emotional decisions.

The bucket strategy was popularized by Harold Evensky and has theoretical underpinnings in asset-liability matching (Leibowitz, Bova, and Hammond, 2010): by matching the duration of assets to the duration of liabilities (spending needs), the portfolio immunizes near-term spending against market volatility. Bucket 1 (cash) matches liabilities in the 0-3 year horizon, where certainty is paramount. Bucket 2 (bonds) matches the 3-10 year horizon, where moderate growth and low volatility are appropriate. Bucket 3 (stocks) matches the 10+ year horizon, where growth is essential and short-term volatility is irrelevant. Pfau and Kitces (2014) evaluated the bucket strategy's risk-reduction properties and found that while the bucket approach does not improve mathematical expected returns relative to a static allocation with systematic withdrawals, it provides substantial psychological benefits: retirees using the bucket approach report lower anxiety, fewer impulse-driven changes, and higher satisfaction. Estrada (2015) showed that the bucket approach with periodic refilling (moving money from Bucket 3 to Bucket 2 to Bucket 1 based on thresholds) approximates the optimal dynamic withdrawal strategy: by delaying stock sales until recovery, the portfolio avoids selling depreciated assets (the sequence-of-returns risk that destroys retirement portfolios). The bucket approach is essentially a heuristic implementation of the more complex dynamic programming solution -- simpler to implement and understand, with comparable outcomes.
